SCRAP-SEPABATING APPARATUS FOR DOUGH-CUTTING AND SIMILAR MACHINES.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed February 7, 1914. Serial No. 817,221.

To all whom it may concern Be it known that we, JOHN CARR and GEORGESAMUEL BAKER, subjects of the King of England, both residing in London,in England, have invented certain new and useful Improvements inScrap-Separating Apparatus for Dough- Cutting and Similar Machines, ofwhich the following is a specification.

This invention relates to scrap separating apparatus for dough cuttingand similar machines used for example in the manufacture of biscuits.

According to the present invention the dough is passed on a main webover a cutting table and the blanks out while the dough is on said web,the latter then continuing directly to the point of separation of theblanks from the scrap and being deflected, while the scrap passes onto asecond web, this construction rendering the apparatus very simple andinsuring the correct or positive movement of the blanks which remain onthe same web throughout the cutting and separating operations.

The invention further comprises means whereby the scrap is supportedthroughout its entire distance of travel from the point where it isseparated from the biscuits to the point where it is collected, forexample in a depositing receptacle, and to this end the web orequivalent which receives the scrap from the main web is adapted toconvey said scrap between itself and the. periphery of a revoluble drumfor a certain distance after which the scrap is supported by said drumuntil collected therefrom.

The invention also comprises certain details of construction andarrangement of parts all as hereinafter fully described and pointed outin the appended claim.

The invention is illustrated in the accompanying drawing, which is aside elevation of an embodiment of the improved scrap separatingapparatus applied to so much of a biscuit cutting machine as isnecessary for comprehension of the invention.

In said drawing a designates the cuttingtable or frame of the machineand b the panning-table or frame of a conventional form of biscuitmachine. The dough travels along the main web a which passes over thecutting table and then over a knife edge a at the end of said table andabout a similar knife edge 6 adjacent the panning table, the web a beinggiven a suitable angle of inclination between said two knife edges toproduce a more or less sharp downward deflection at the point a wherethe scrap is separated from the biscuits. Adjacent said point ofseparation at a minimum distance therefrom to permit passage of the mainweb and the biscuits thereon is a third edge or equivalent 0 adjustablymounted in bearings carried by standards or side frames (Z shown assupported by the panning table and supporting all the elements of thescrap separating device proper. Passing about said edge a which ispreferably provided at each side with guides or flanges 0 is a scrapsupporting web (Z which passes horizontally in or about the same planeas the main web a and about a guide roller c, thence about a drivingroller 0 and from the latter par tially around the periphery of arevoluble drum 6 to the top thereof, thence about guide rollers 6 0 6the former of which is mounted to slide in bearings f under the actionof a web tensioning spring f then from the guide roller 6 through aguiding device comprising a block 9 and spring plate g and from thelatter over a further guide roller 0 back to its commencement at theknife edge 0. Adjacent the drum 6 at the side thereof opposite the web6Z1, there is mounted on a bracket h extending from the standards 0? ascrap receiving receptacle h into which the scrap is passed from thedrum by a scraper k mounted in arms 7L3 supported by the bracket.

The action of the apparatus is as follows The scrap, traveling alongwith the biscuits on the main web a is carried, at the point adjacentthe knife edges a and c, horizontally or without appreciable deflectiononto the web (Z1 and is conveyed by the latter between itself and theperiphery of the drum against which it is held by the portion of the webpassing thereabout until it reaches the top of said drum, from whichpoint it is supported by the drum itself until it reaches the scraper 72which deflects the scrap and allows same to accumulate in the receptacleh from which it may be removed by any appropriate means.

Instead of the receptacle a traveling belt may be used to take away thescrap to a desired point.

That part of the drum about which the web passes is preferably partlyinclosed by housings or casings j forming parts of the standards or sideframes d and supporting the bearings for the guide rollers 6 and 6 Thescrap runs horizontally for a distance, and afterward is supportedbetween the drum and the web and carried to a higher level, so that itcan be collected and put in a receiver or carried elsewhere. It will beapparent that by having two or more rollers with a web passing oversame, that the scrap might be carried away from the drum to a break ormixer as might be required.

It will thus be seen that the scrap is not liable to fracture at thepoint of separation from the biscuits owing to its movement in itsinitial plane when separated and having to traverse a gap of minimumwidth and that it is positively supported throughout the whole distanceof its travel from the time of leaving the cutting table or equivalentto its final deposition in the collecting receptacle. i

What we claim as our invention and desire to secure by Letters Patent ofthe United States is In a scrap separating apparatus, the combination ofa cutting table, a substantially horizontally disposed web passing oversaid table on which the blanks are cut from the material and on whichsaid blanks and scrap travel together, means for downwardly deflectingsaid web at a point of its length to convey the blanks forward, a secondweb spaced only sufliciently from said first men tioned web to permitpassage of the blanks at the point of deflection of said web, saidsecond web receiving and conveying the scrap in a horizontal plane, adrum about the periphery of which the scrap receiving web passes toconvey the scrap between said web and drum for a substantial portion ofsaid periphery, the scrap being finally supported on the drum alone, ascraper for removing the scrap from said drum, and means for collectingthe scrap removed by the scraper.

In witness whereof we have signed this specification in the presence oftwo witnesses.
